Preliminary
SV3639-001
This is a new and advanced class of VCSELs from Honeywell having
dramatically reduced electrical power consumption, reduced variation with
temperature and excellent reliability. Honeywell Single Mode VCSELS have
been engineered to achieve a good balance between threshold current and
reliability. The 850nm single mode VCSELs are available in all of the current
Honeywell VCSEL packaging configurations such as the TO46, and surface
mount components. Custom packaging designs are also available..
The SV3639 combines many of the desired features of an LED and the
advantages of a laser diode operating in a single longitudinal mode and a single
transverse mode. The VCSEL provides increased power output at low drive
currents. As the current increases above its threshold, the light intensity
increases proportionally.

NOTICE
Stresses greater than those listed under
“Absolute Maximum Ratings” may cause
permanent damage to the device. This is
a stress rating only and functional
operation of the device at these or any
other conditions above those indicated in
the operations section for extended
periods of time may affect reliability.

Notes:
1. Minimum threshold occurs above room temperature.

NOTICE
The inherent design of this component causes it to be
sensitive to electrostatic discharge (ESD). To prevent ESD-
induced damage and/or degradation to equipment, take normal
ESD precautions when handling this product

current at an appropriate level, then adjusting
the temperature.
•
While they are designed to stay single mode
over the whole operating current range, at very
high currents they may become multi-mode,
increasing the spectral width and the beam
divergence.
Despite their low operating currents, these
VCSELs can emit sufficient power to be
categorized as Class 1M lasers, and should be
treated with the usual precautions.
They are even more sensitive to ESD than are
multi-mode VCSELs or CD lasers.
They operate at currents typically below 5 mA
and should never be driven at much higher
currents.
The spectral peak shifts significantly with
current, but shifts only slowly with ambient
temperature. Operation at a particular
wavelength can be achieved by first setting the
